Should vaccines be mandated?

Question of the Week
From The Star-Ledger Parental Guidance page for March 9

The Centers for Disease Control has recommended all children in the nation get flu vaccines. Several groups, however, oppose mandatory vaccines because of concerns they are linked to autism and other health problems. In New Jersey, there is a "conscientious exemption" bill that would allow parents to refuse the vaccines.

Do you think mandatory vaccines of any kind, including the flu, are a good idea?
